Joe Biden's 2020 signals

He’s got three political organizations up and running: the Penn Biden Center for Diplomacy and Global Engagement, his domestic policy institute in Delaware and American Possibilities, his political action committee.

Some of Biden’s longtime advisers have privately weighed the possibility of Biden serving only one term as president, if he runs and gets elected, allowing his running mate to take over in 2024, AP notes.

He’s been more consistently outspoken about Trump, setting himself up as a formidable Democratic challenger. Last week’s University of New Hampshire poll puts him as the favorite 2020 candidate among Democratic voters.
